http://forum.soundillusions.net/showthread.php?t=54724 I know I posted this over on CA.com, but just in case you didn't see it... This isn't MECA-sponsored, but should be good to get out (away from the forums, hehe ) and see some people/installs. I had better see some of the B'burg crew out there

Hey everyone. What do you think would be the best for music and spl box size for a 15" Zcon. Been looking but can't find the suggested box sizes on here. Thanks guys.

I am looking for someone to build a enclosure for my 15" ssa xcon. It needs to be 4 cubic feet tuned to 29hz, i'd like a flared slot port, in a standard rectangular enclosure with dark charcoal carpet, with a rectangular 10" window on the top showing off the insides (which means the insides need to look nice to enough to show off), so what would this run??? any offers? Also to add I would like it to only be 16" in height and no more than 35" in width, and I would like it if you could let me know what the end result on the depth would be?

After watching YouTube and attending a few myself. It appears competitions make the hobby kind of sour. Online were all friends, then comp day rolls around and it's like the wild wild west. I've seen a lot of friends and drama start and end from these "comps" Almost to the point I don't even like attending them. I go to shows to talk interact and enjoy the hobby. I just feel like comps get way too serious. FTLOB!!!!

What all do I need to model my zcon for the new enclosure? About to start building and want to have the enclosure design as good as I can.

Please, I know someone out there has a user manual for a 7949. Its all I want for x-mas. If you can just scan me the pages that refer to the units features and fubctions, setup and use. Thanks, Joe. P P.S. I've been searching everywhere forever now Thanks

the back window on my 2000 ford Explorer is Mage Flexxing !!! what can be done to stop the spl from leaking out ???

I had to get a pic on my cell, only camera I had at the time.

My shop teacher has a 1 inch thick piece of plexiglass, and he said if I can find way to cut it, I can have it. I have a tablesaw, circularsaw, router, and a jigsaw, but wasn't sure if any of them would cut it. Will they?

OK, so I am hoping that some box building gurus can help me stop pulling may hair out trying to decide on what box design and subwoofer choice I should go with. As you know, the Toyota MR2 is a very small car with not much room behind its only 2 seats. It is mid engine, so the trunk in the back is of no use to me for subs. they must go right behind the seats in a wedge style box. Here is an MR2 and a pic of the space behind the seats: So I listen to all kinds of music literally, well maybe not country so much, but lots of stuff. I want it to sound musically nice but definitely want to produce as much SPL or should I say """SQL""" as possible if s…

I'm going to be building a small aero ported box for a friend soon, but he doesn't want to spend the extra few dollars to buy real aero's. He wants to go with just straight PVC pipe instead. Yes, I explained port noise and the advantages of having flared ports. Anyway, what's the best way to mount PVC pipe externally on a box? There's no flare to screw into the wood, only a straight pipe to sit inside the cutout. I'm having trouble trying to figure out the most stable and secure way of attaching the PVC. Thoughts?

Well I got a couple more 15" Rockford Fosgate RFR2215 Power DVC subs.. now I am ready to do my four 15's setup. At Slamology I got a 148.1 in DB Drag with 2 15's and 2 12's at 44hz. My goal with this new box build with four 15's is to hit 150db mark. I recently just started playing with Bass Box Pro and Google Sketchup and I have come up with a Design in Bass Box Pro and then tried to Model it the best I could in Google Sketchup so here it is. This will be powered by a T40001bd. 12 cubes after sub,port,bracing displacement with 1" MDF 4 6" PVC Ports 10.5" Long to get a tune at 38.01hz There will be a total of 9 1" Dowel rods for bracing in the box 4 from top to bottom 3…

Thanks in advance for the help. Alright I am planning on getting a 12" Fi Q D2 and already ordered a sundown SAZ-1000D to power it. I've never built a box before and I dont trust the audio shop here. I want to build a L shaped ported box. Its going in a 1997 chevy blazer so I have room. First should I go sub up port back or sub back port back? What are the benefits of each keep in mind I'm not going for spl. According to Fi "Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume." So I…

The Box design i used from a guy from SMD didnt pan out so well, i honestly think the port length was longer than in my plan.... It sounds like it tuned to 42hz instead of 32hz. That being said im hoping SSA forum can help!! Keep in mind id really like to keep the box either as wide and shallow or flat/wide/deep as possible. Basically im trying to fit the golf clubs in the back, either in front of the box, or on top. 12" Fi Q on ~1600RMS tuned to 30ish hz. thanks for the help fellas/ladies

Hey, I am looking to build an enclosure for one Sundown E-12 in the near future. I plan on putting it into a 2.5 cubic foot enclosure. (PWK recommends an enclosure for the E-12 of at least 60L (~2.1 cu ft) for a more linear response) I also want to use a 4" aeroport (precision port) 10.25 inches long for a tuning of 32 Hz. I think my question is, would it be alright to tune this box to 30 Hz? All it would require is 12 of port length compared to the ten and a quarter. I'm just slightly confused because I have heard not to tune too far below a subs res. freq. because it might cause roll-off right at the tuning. If it sounds stupid, that's because I read it once somewhere o…

Hello all, I'm new to this forum, but not to car audio. I am however new to the Sundown woofers. I'm hoping you all can lend some help and thank you in advance on my enclosure design. What I have is an 05 Acura TL I'm doin a pair of Sundown SA12s in the trunk. Subs to be fired foward and a 6in Aero either out the back or side. I have tried several enclosures with foward fired subs & port, but the car just did not really like it. Last setup was a single CV Stroker12, power was supplied by an O.S. USamps VLX400 1ohm mono. I had good results with two 4in PVC ports fired back, Sub obviously foward. Then tried a 6in Aero out the drivers side of box. The Aero was slightly b…

I have a 12" GCON in a 2.5ft^3 enclosure tuned to 32hz. I have been lacking in response toward higher frequencies and was curious to know where the drop was happening, as it is quite a steep slope. I was playing with a tone generator this evening and from 28 to 50hz sounded amazing but as soon as I hit 53hz I lost significant dbs. There was another significant drop at 60hz. Is this due to my box tuning? Can a ported enclosure be expected to produce these frequencies with significant spl? What can I do to get these frequencies to play? Separate subs dedicated to that range? box position doesn't seem to make a difference. Vehicle is a 96 Honda accord sedan.

Has anyone ever heard of this guy? And are his designs worth the money? His website is: PWK Designs

Posted this in the hop since there was some vinyl talk this morn, but need some help in figuring out how to finish the vinyl off after it is stretched and glued to the front. There is no place to "staple" the vinyl to the back of the pods so how would you attach it? I have never done this before, but have some really stretchy vinyl and 3M 77 Spray adhesive (and others, but thought this was best). Any recommendations on how to finish or attach the vinyl to the backside of the tweeter pods? As a reference for size the whole is less than 2" and the edges of the pod are about a 1/4". These will be mounted in the stock sail panel locations.

when setting your gains on amps why cant you turn them all the way up. and if you have them less then half way are you still getting the rated power of the amp. say if the amp is 1000w RMS are you getting that no matter what the gains are set too..... jamie

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5091 I saw this on ROE and couldn't beleive the price! Are these like last years version of the 61i that is currently on the CDT "gold" web site. I remember old CDT eurosport, and only heard them once, I was pretty impressed but it was a 3 way. I just don't have that kind of cash ATM, and won't for a while with all the rest on my build up. Bump if anyone has experience with these? I might jump on this and let the H/U issue wait.. if these are a value anyone want to borrow me another 300 bucks so I can get 2 sets I would hate to miss out on sucha pwn sauce deal if these are in fact good?? lol I'm looking for some…

Anyone know of of a snug fitting dual sub box that'll fit in back of the second seats? Im taking out far back seats want to leave middle seats. Only wanting to do dual 15" subs. Should they be enclosed also?
